Kurzfassung

From the interpretation of the two-dimensional elliptic grid generation equation in conservative form as a force balance a method is devised for an iterative update of the control functions, which drives the grid towards orthogonality, not only at the boundaries but in the total field. The method has also been successfully used to effectively reduce grid line skewness in the physical domain, when adaptation is performed in a parametric domain.It is readily implemented into existing codes and easily extended to three dimensions.
